flex 合并单元格

flex中对于合并单元格没有很好的解决方案,有的可能会用OLAPDataGrid来实现,不过感觉效果还不是很好,下面有个例子:
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

        import mx.olap.IOLAPQuery;
        import mx.olap.IOLAPQueryAxis;
        import mx.olap.IOLAPCube;

不过后来在网上看到MecGrid感觉还不错,所以拿上来与大家分享.
首先得把它的swc加进来,加到flex build path里面.
下面就是例子:

    fontSize: 8;
    verticalScrollBarStyleName: filterRendererScrollStyle;
}

.filterRendererScrollStyle {

    downArrowOverSkin: Embed(source="/assets/downArrow.png");
    downArrowDownSkin: Embed(source="/assets/downArrow.png");
    upArrowUpSkin: Embed(source="/assets/upArrow.png");

OLAPDataGrid好像是分组统计用的，并没有把单元格合并。也许用传统的HTML画这样的表格是最好的选择了。。。

真的只能用HTML画这样的表格了吗？？不知道还有没有其它方法。
